5407.43.10.00 - The thread count of which per cm (treating multiple (folded) or cabled yarns as single threads) is over 69 but not over 142 in the warp and over 31 but not over 71 in the filling (620) 🖩

This HTS category, 5407.43.10.00, specifically covers woven fabrics composed of synthetic filament yarns, with the defining characteristic being their thread count. These fabrics must contain 85 percent or more by weight of nylon or other polyamide filaments. The crucial thread count criteria for classification within this subcategory are a warp thread count exceeding 69 but not exceeding 142 per centimeter, and a filling thread count exceeding 31 but not exceeding 71 per centimeter. Multiple or cabled yarns are treated as single threads for this count.

This specific classification is distinguished from its sibling category, 5407.43.20, which is also designated for "Other" woven fabrics of nylon or polyamide filaments with yarns of different colors but does not meet the precise thread count specifications outlined here. Therefore, any woven fabric of synthetic filament yarn, primarily composed of nylon or polyamides and featuring yarns of varying colors, will fall into this category if and only if it satisfies the specified warp and filling thread density thresholds.

As this HTS code represents a leaf node, there are no further subcategories. The classification is determined solely by the material composition (nylon or other polyamides), the use of yarns of different colors, and the precise thread count in both the warp and filling directions. This level of specificity ensures that fabrics with distinct structural properties, and potentially different end-uses and values, are appropriately categorized for customs purposes.
